12V DC Outlets on Inverters
The Ac outputs are regulated and at the proper voltage and frequency (120 volts 60Hz). With no load I measure 19.4 to 25 volts dc depending on low or high idle. With the output connected to a battery I get 17.2 to 20.4 volts DC depending on low or high idle. I have called tech support a few times about this.
Yes, with no resistance on the outlet, the voltage will be this high. If you connect an automotive or power sport battery to the outlet for example, the voltage will drop down to about 17V DC. If you are using a portable charging device to charge a phone for example, the adapter will have the proper resistors to supply appropriate voltage and amperage to your devices for charging.
Champion Inverter models beginning with 200XXX, such as model 200951, do feature regulated 12V DC output.
